To all whon z may concern:

Be it known that I, AUeUsr B. HoHMA'NN e-Q siding at Richmond Hill, county. of Queens,

. vation showing the modified forms. of the deing the glass tube of such an instrument against injury. By pressing block a tightly upon theand State of New York, have invented certain new and useful Improvements in Means for Securing Heat, Pressure, and other Measuring Instruments in Central .Position in Bot.- tles and other Vessels, of which improve: ments the following is a full, clear, and exact specification, reference being had to, the accompanying drawings, wherein Figural is an :elevation of abottle provided with my improveddevice for securing a thermometer in' central'position therein,

Fig. 2 is an enlarged viewof the .holder for such measuring instrument forming part of my. invention. Fig. 3 is a' sectional view thereof. Figs. 4 and 5 are plan views of one form of the fastening:device. ..Fig 6 is a simia lar. view like Fig. 3, showing the packing in the shape of astopper for closing the mouth of the bottle.

strument. Fig. 8is'an elevation'of'a modified form of the device for securingthe instrumerit-holder to the bottle; Figu9'is an elevices' illustrated in Figs'..'? and 8 .joined together and with a support for the instrument.

My invention relatesto means ,forsecuring instrumentsas, forinstance, thermometers,

pressure-gages, & c.in a central position.

within a bottle and in such. manner that the neck of the bottle is thereby hermetically sealed.

In Fig. l of the drawings, A designates a bottle containing liquid to be sterilized, and B designates the upper end of agthermometer inserted in the bottle. This thermometer a is set in a holder, whichalso serves for hermetically closing the mouth of a bottle or the 2115- erture of a vessel to which it is applied. The holdercomprises a perforated block at, having an enlarged base a, terminating'into a circus.

lar flange at. In this base a ametallic tube 7) (called armor) is secured, open on both ends and perforated at 6. Thefupper portion of block a is internally screw-threaded, and a perforated and also internally-screw-threaded..

Fig. 7. 'is an elevation of a. modified construction of the holder of the in collar 6 is screwed therein. this collar 0 tube d ,(the other part ofthe armor) is screwed. The terminus of this tube d is externally screwthreaded, and cap 6 is screwed thereon. Thermometer B (or other, measuring instrument) is inserted in tubes 6 and d and is held in position relatively thereto byjits enlarged head f resting upon the end of tube 0? and held between it and the cap 6. A packing-ring g is fitted upon the thermometer B and fills the bore in block a. Collar 0 serves to compress thisjpacking g so as to make the joint between the thermometer and the block a absolutelyairtight. The base of block a is shaped as the form of a head of a bottle or the flange. of the aperture of other similar vessel requires. Flange a surrounding the base, formsv a, recess wherein the compressible packing It is inserted. This packing rests on the mouth of the bottle (or the aperture of other vessel) when the instrument is set therein. Packing hmay also be made in the form of a stopper shown in'Fig. 63' but the form shown in Figs. 1, 2, and 3 is'preferable, and it may be used directly on the glass tube of an instrument, (for instance, thermometer) without the metallic tube Z2, which is used as an armor forprotectof the clamp, consisting, preferably, of three vflanged segments i, joined togetherby screws is, is afiiXjed to'the bottle underneath its head. To each one ofthe three segments ea screwl is hinged-at m, and upon each of the screws Z ,a thumb-screw nut n is fitted. Cap 0 isprovided with lugs p, whose position corresponds to that of the screws Z. This clevice is to be used on any' form of bottles or other vessels having an enlarged head. To aflix the thermometer to a bottle, segments 1; are joined together around the neck thereof, as shown in Fig. 1, i i

and cap 0 if not made integral with the block a is set thereon; Then screws Z are slid between the" prongs of lugs 39 and the thumbscrews n screwed thereon to press block aupon the mouth of the bottle. instrumenta thermometer,pressure-gage, or whatever it may 'beis safely and reliably secured in central position in the; bottle and is so secured that it will alwaysremain in that central position no, matter whether the bottle isstanding upright or laid down horizontally;

The modified construction shown in Fig. 7 is adapted for use in connectionwith bottles which are not provided with enlarged heads or when for some reason or another the clamp composed of the segmental parts shown in' Fig. 4: cannot be used. In this case- I use 1n place of segments 71 a frame composed of plate-z", shaped in conformity with the bottom of the bottle, and screw-threaded posts Z integral therewith or hinged thereto in the same manner as the screwsl are hinged to the segments 2' of the ring.-- Posts Z may be joined together-by ties s, and two, three, or more of such ties may be used, as the shape and dimensions of the vessel-may require. i The ends of the posts Z are screw-threaded and fitted into lugs 10 of cap' 0, being of course hinged correspondingly to the position of these lugs. Sometimes-for instance, when the bottles are immersed in a tank-it is desirable to support the part of the instrument extending beyond the bottle and to protect it against bending or breaking when in use. To facilitate such an arrangement,

the cap designated 0 in the aforedescribed' arrangement of my device is made in the form shown in Fig. 8. As there shown the capo" is provided with wings t, having bores u for aflixing them to the support for the instrument, and the lugs 10' are produced by bending the ends of the wings at right angles to the plane of the wings. In these lugs slots or holes are provided for the screw-threaded ends of the posts Z, according to what form of the device for securingthe bottle thereto is used, In Fig. 9 the modified form of cap 0 shown in Fig. 7 is used in connection'with the modified form of the bottle-holding device I illustrated in Fig. 8, as hereinbefore explained.

In the sterilizing process it is of great importance that the temperature'oftheliquid sub ected to the sterilizing process be exactly ascertamed. As a rule the sterilizing is donein 'a tank containing hot water. The heat of this water is communicated to the liquid within the bottle through the glass, The heat-acts I upon the liquid within the bottle from the walls thereof and toward the center, and it is therefore of the utmost importance for the sterilizing process to ascertain the degree of possible.

In this mannenthe" bottle is firmly maintained in an uprightposition, because a deflection therefrom causes the thermometer to swing to one side of the bottle, where the liquid is naturally more 'heatedi F0r this reason such apparatus is not as reliable. By means of my improved device the-thermometer is'sfafelyifixedfin a t c a o itiwi h bqtt sqthat it not be deflected, no matter what position is given to the bottle..

This -improveddevice= fcan' also-with equal advantage be used for securing a self-registering thermometerin. such central position in the bottle. The device for'that'pur'pose is the same'except that the upper tube 0? and cap 6 are omitted and in place of the screw- 7 threaded collar p 'a'plugis u ed; V Thering com-posed 20f segments may be made up of two or four and, in fac t,any num 'ber of such segments instead of three, as'shown in the drawings; but the use of three parts, with the screws arranged as shown in the drawings,

possesses the advantage that the adjusting and securing in position of the thermometer in the center of the bottle is thereby facilitated. If,

for instance, the headof thebottle shouldnot be exactly even, the adjustment'of the 'instrument in central position w'ould be more difficult ifonly two or imore than three screws were used. 1 If, however, three :screws are used, any deflection of the instrument 1 from the axial line ofthe-bottle caused by .the uneven-headofthe bottles can be corrected by -mani pulating'the screws; H r
